Subject: | TZH:TZM |
Timezone format elements in Convert::NLS_DATA_FORMAT are:
TZHTZM=> '%z', # time zone hour offset from UTC
TZH => '%z',
TZR => '%Z', # time zone name
TZHTZM, TZR works fine.
TZH should return just hour offset but currently it's the same as TZHTZM.
TZM is not implemented at all.

POSIX has no equivalents to TZH or TZM so there is no way to implement
it but it will probably make sence to die or warn if somebody tries to
use TZH or TZM alone as on the oracle page there are a lot of examples
like 'HH:MI:SS.FFTZH:TZM'.
